Abstract

Dans une mécanique d'armure dans laquelle la sélection des crochets s'effectue par rotation de leurs tiges de façon à présenter leurs becs aux lames des cadres de griffes ou au contraire à les effacer, une lamelle élastique (26) est interposée entre l'oeillet (13) de chaque crochet et la lisse (14) correspondante. Chaque lame élastique traverse la fente (26) d'une planche de guidage (25). Chaque lame agit à l'instar d'un ressort de rappel.In an armor mechanism in which the selection of the hooks is effected by rotation of their rods so as to present their beaks to the blades of the claw frames or on the contrary to erase them, an elastic lamella (26) is interposed between the eyelet (13) of each hook and the corresponding beam (14). Each elastic blade passes through the slot (26) of a guide board (25). Each blade acts like a return spring.

Description

Demande divisionnaire correspondant à la demande de brevet européen 83420119.6 publiée sous le numéro 0100288.Divisional application corresponding to European patent application 83420119.6 published under the number 0100288.

La présente invention se réfère aux mécaniques d'armure à double lève dans lesquelles les crochets pris par l'un des deux cadres de griffes qui se déplacent verticalement en sens inverse l'un de l'autre, se décalent angulairement autour de l'axe de leur tige de manière à échapper à l'autre cadre sans qu'on ait à prolonger à cet effet la durée de ce qu'on appelle la presse, c'est-à-dire de la phase durant laquelle lesdits crochets sont sélectivement repoussés par les aiguilles correspondantes.The present invention refers to the mechanical double armor armor in which the hooks taken by one of the two claw frames which move vertically in opposite directions to each other, are angularly offset around the axis of their rod so as to escape from the other frame without having to extend for this purpose the duration of what is called the press, that is to say of the phase during which said hooks are selectively pushed back by the corresponding needles.

Cette mécanique, dont on peut dire qu'elle est à crochets orientables, a été décrite dans le document FR.A.2 179 655 du 11 Avril 1972. Grâce à la réduction du temps de presse, elle s'est avérée pouvoir fonctionner à des cadences nettement supérieures à celles des mécaniques classiques. Toutefois l'expérience a montré qu'avec des métiers marchant à très grande vitesse on assistait parfois à des fautes de sélection. Grâce à une étude minutieuse du comportement des crochets sur de tels métiers, on a pu déterminer que cela provenait d'une orientation défectueuse de ceux-ci sur les lames du cadre de retenue. Ces lames devraient normalement amener les becs qu'elles supportent à se trouver orientés exactement dans des plans verticaux perpendiculaires à elles ; or on relève parfois de légères déviations angulaires momentanées que sur les métiers du genre en question peuvent atteindre des valeurs telles que la levée sélective des crochets s'en trouve affectée.This mechanism, which can be said to have adjustable hooks, was described in document FR.A.2 179 655 of April 11, 1972. Thanks to the reduction in press time, it has proved to be able to operate at rates significantly higher than those of conventional mechanics. However, experience has shown that with trades working at very high speed, we sometimes witness selection mistakes. Thanks to a careful study of the behavior of the hooks on such looms, we were able to determine that it came from a defective orientation of these on the blades of the retaining frame. These blades should normally cause the beaks they support to be oriented exactly in vertical planes perpendicular to them; however, there are sometimes slight momentary angular deviations which, in the trades of the genre in question, can reach values such that the selective lifting of the hooks is affected.

La présente invention vise à remédier à cet inconvénient.The present invention aims to remedy this drawback.

L'on interpose à cet effet entre l'extrémité inférieure du crochet et la lisse correspondante une lamelle élastique qui coulisse par ailleurs dans une fente d'une planche de guidage Fixe prévue au-dessous de la planche de fond précitée. Ainsi cette lamelle tend constamment à rappeler le crochet à l'orientation de repos prévue. Son élasticité permet les rotations de 45° de la tige autour de son axe sans leur opposer une résistance gênante, mais elle détermine un couple de rappel qui évite ou limite toute rotation exagérée et contribue à ramener le crochet à son orientation de repos.For this purpose, there is interposed between the lower end of the hook and the corresponding rail an elastic strip which also slides in a slot of a fixed guide board provided below the bottom board. cited above. Thus this strip constantly tends to recall the hook to the intended rest orientation. Its elasticity allows rotations of 45 ° of the rod around its axis without opposing an annoying resistance, but it determines a restoring torque which avoids or limits any exaggerated rotation and contributes to bringing the hook back to its rest orientation.

Ainsi conformément à l'invention entre l'oeillet ou analogue de l'extrémité inférieure de chaque crochet et la lisse correspondante est interposée une lamelle élastique et entre la planche de fond et le niveau de l'extrémité inférieure de cette lamette quand le crochet intéressé est en position levée, il est prévu une planche de guidage percée de fentes individuelles pour le passage desdites lamelles, l'orientation de ces fentes étant telle que les lamelles ne soient soumises à aucun couple de trosion quand le crochet se trouve à sa position abaissée de repos.Thus in accordance with the invention between the eyelet or the like of the lower end of each hook and the corresponding heddle is interposed an elastic strip and between the bottom board and the level of the lower end of this strip when the hook concerned is in the raised position, a guide board is provided pierced with individual slots for the passage of said strips, the orientation of these slots being such that the strips are not subjected to any torque when the hook is in its lowered position rest.

Le dessin annexé, donné à titre d'exemple, permettra de mieux comprendre l'invention, les caractéristiques qu'elle présente et les avantages qu'elle est susceptible de procurer :

  • Fig. 1 est une vue schématisée d'une mécanique suivant l'invention, un seul des crochets de celle-ci étant représenté.
  • Fig. 2 est une vue en élévation de ce crochet.
  • Fig. 3 en est une vue en plan.
  • Fig. 4 est une vue en perspective à grande échelle montrant la partie basse d'un crochet, la lamelle élastique qui lui est attachée, ainsi que la planche de fond et la planche de guidage qu'elle traverse.
The appended drawing, given by way of example, will allow a better understanding of the invention, the characteristics which it presents and the advantages which it is capable of providing:
  • Fig. 1 is a schematic view of a mechanism according to the invention, only one of the hooks thereof being shown.
  • Fig. 2 is an elevational view of this hook.
  • Fig. 3 is a plan view thereof.
  • Fig. 4 is a perspective view on a large scale showing the lower part of a hook, the elastic strip attached to it, as well as the bottom board and the guide board through which it passes.

On a schématisé en fig. 1 une mécanique comportant application de la présente invention. Celle-ci comprend des crochets à tige unique dont un seul a été représenté en 1. Chacun d'eux est commandé à la sélection par une aiguille 2 comportant une boucle 2a qui entoure sa tige. Les aiguilles 2 traversent une plaque 3 et reçoivent l'action sélective de butoirs 4 guidés par une autre plaque perforée 5. A chaque aiguille 4 est associée une aiguillette 6, laquelle est propre à coopérer avec le papier perforé 7 de la mécanique. Lorsqu'une aiguillette 6 rencontre un plein du papier, elle est soulevée et le butoir 4 entre ainsi en contact avec une butée 8 qui oscille horizontalement, l'aiguille 2 est alors repoussée à l'encontre de la réaction d'un ressort R en entraînant le crochet 1 considéré.We have schematized in fig. 1 mechanics with application of the present invention. This comprises hooks with a single rod, only one of which has been shown at 1. Each of them is controlled for selection by a needle 2 comprising a loop 2a which surrounds its rod. The needles 2 pass through a plate 3 and receive the selective action of stops 4 guided by another perforated plate 5. Each needle 4 is associated with a needle 6, which is able to cooperate with the perforated paper 7 of the mechanics. When a needle 6 meets a full of paper, it is raised and the stopper 4 thus comes into contact with a stopper 8 which oscillates horizontally, the needle 2 is then pushed back against the reaction of a spring R in causing the hook 1 considered.

Dans le cas d'un trou palpé par l'aiguillette, le butoir 4 échappe à l'action de la butée 8 si bien que le crochet n'est pas poussé par l'aiguille 2.In the case of a hole palpated by the needle, the stopper 4 escapes the action of the stopper 8 so that the hook is not pushed by the needle 2.

En fig. 2 et 3 l'on a référencé 9 la tige d'un crochet. Celle-ci porte à son extrémité supérieure un premier bec principal 10 (fig. 2), puis un peu plus bas un second bec principal 11, orienté en plan (fig. 3) à 90° du précédent, puis beaucoup plus bas encore un bec de retenue 12 disposé en plan suivant la bissectrice de l'angle des becs précédents. L'extrémité inférieure de la tige 9 est enfin recourbée sur elle-même sous la forme d'un oeillet 13, lequel est incomplétement fermé dans la forme d'exécution représentée, cet oeillet étant destiné à être relié à la lisse correspondante 14 (fig. 1) à la façon qu'on exposera plus loin.In fig. 2 and 3 we referenced 9 the rod of a hook. It carries at its upper end a first main spout 10 (fig. 2), then a little lower a second main spout 11, oriented in plan (fig. 3) at 90 ° from the previous one, then much lower still a retaining spout 12 disposed in plan along the bisector of the angle of the preceding spouts. The lower end of the rod 9 is finally bent over itself in the form of an eyelet 13, which is incompletely closed in the embodiment shown, this eyelet being intended to be connected to the corresponding heald 14 (fig 1) in the way that will be explained later.

Les becs principaux 10 et 11 sont destinés à coopérer avec les lames respectives 15 du cadre de griffes supérieur 16, et 17 du cadre de griffes inférieur 18, ces deux cadres allant et venant verticalement en sens inverse l'un de l'autre. Quant au bec de retenue, il coopère de son côté avec l'une des lames 19 du cadre fixe de pas ouvert 20.The main spouts 10 and 11 are intended to cooperate with the respective blades 15 of the upper claw frame 16, and 17 of the lower claw frame 18, these two frames coming and going vertically in opposite directions to each other. As for the retaining spout, it cooperates on its side with one of the blades 19 of the fixed frame of open pitch 20.

Telle qu'on l'a décrite jusqu'ici la mécanique à crochets orientables suivant la présente invention est semblable à U ! celle décrite dans le brevet mentionné plus haut.As described heretofore, the mechanical with adjustable hooks according to the present invention is similar U! that described in the patent mentioned above.

Toutefois dans cette mécanique antérieure les crochets 1 non soulevés étaient supportés par le moyen d'un second cadre fixe situé au-dessous du cadre de pas ouvert 20 et sur les lames duquel les becs 12 venaient reposer, ces lames assurant leur orientation de repos indiquée en fig. 3, c'est-à-dire le bec de retenue 12 considéré se trouvant exactement dans un plan vertical perpendiculaire aux lames 15, 17 et 19. Il est prévu dans la planche de fond 21 des dépressions 22 dans lesquelles les oeillets 13 viennent se disposer.However in this prior mechanics the hooks 1 not raised were supported by means of a second fixed frame located below the open pitch frame 20 and on the blades of which the nozzles 12 came to rest, these blades ensuring their indicated orientation of rest in fig. 3, that is to say the retaining spout 12 considered lying exactly in a vertical plane perpendicular to the blades 15, 17 and 19. There are provided in the bottom plate 21 depressions 22 in which the eyelets 13 come dispose.

Le fond de la dépression 22 est perforé d'une ouverture circulaire 23 dont le profil vient s'inscrire à l'intérieur de celui 22a de l'entrée de la dépression 22.The bottom of the depression 22 is perforated with a circular opening 23 whose profile is inscribed inside that 22a of the inlet of the depression 22.

A l'oeillet 13 de chaque crochet est par ailleurs accrochée une lamelle élastique 24 (fig. 4) qui traverse l'ouverture 22 et à l'extrémité inférieure de laquelle est fixée la lisse 14 correspondante.On the eyelet 13 of each hook is also hung an elastic strip 24 (fig. 4) which passes through the opening 22 and at the lower end of which the corresponding beam 14 is fixed.

Au-dessous de la planche de fond 21, mais encore au-dessus de l'extrémité inférieure des lamelles 24 correspondant à des crochets en position haute c'est-à-dire qui ont été soulevés par l'un des cadres de griffes (16, 18), il est prévu une planche de guidage 25 (fig. 4) percée de fentes étroites 26 pour le passage desdites lamelles 24. Les fentes 26 sont orientées de façon telle que lorsqu'un crochet repose sur le fond de la dépression 22 correspondante de la planche de fond 21, sa lamelle 24 ne comporte aucune torsion.Below the bottom board 21, but still above the lower end of the strips 24 corresponding to hooks in the high position, that is to say which have been lifted by one of the claw frames ( 16, 18), there is provided a guide board 25 (fig. 4) pierced with narrow slots 26 for the passage of said strips 24. The slots 26 are oriented so that when a hook rests on the bottom of the depression 22 corresponding to the bottom plate 21, its strip 24 has no torsion.

Le fonctionnement est le suivant :

  • Lorsqu'un crochet 1 est au repos, son oeillet inférieure 23 repose dans la dépression 22 correspondante de la planche de fond 21.
The operation is as follows:
  • When a hook 1 is at rest, its lower eyelet 23 rests in the corresponding depression 22 of the bottom board 21.

A partir de cette position de repos, lorsque le crochet 1 considéré à été sélectionné, tout se passe comme indiqué dans le brevet précité, la partie de la lamelle 24 située entre la planche de guidagé 25 et l'oeillet 13 n'opposant qu'une très faible réaction de torsion à la rotation de 45° de la tige 9 autour de son axe dans un sens ou dans l'autre. Donc quand l'un des becs principaux, 10 par exemple, a été pris par un cadre de griffes et est soulevé puis abaissé par celui-ci, l'autre 11 est pratiquement orienté parallèlement aux lames et ne risque nullement d'être accroché par l'une de celles de l'autre cadre.From this rest position, when the hook 1 considered has been selected, everything takes place as indicated in the aforementioned patent, the part of the strip 24 located between the guide board 25 and the eyelet 13 opposing only a very weak torsional reaction to the 45 ° rotation of the rod 9 around its axis in one direction or the other. So when one of the main spouts, 10 for example, has been taken by a frame of claws and is raised and lowered by it, the other 11 is practically oriented parallel to the blades and does not risk being hooked by one of those in the other frame.

La lamelle élastique 24 exerce sur l'oeillet 13 un couple de rappel qui tend à précisément ramener le crochet à la position angulaire de fig. 3 et qui contribue donc à assurer cette orientation correcte de celui-ci au repos. En outre cette lamelle, dont le couple de réaction augmente rapidement avec l'angle de torsion, s'oppose à toute rotation exagérée de la tige 9 qui pourrait aboutir à ce que l'un des becs principaux puisse rencontrer une lame destinée à un autre crochet (par exemple la lame située au- dessus de la tige 9 en fig. 3).The elastic strip 24 exerts on the eyelet 13 a return torque which tends to precisely bring the hook back to the angular position of FIG. 3 and which therefore contributes to ensuring this correct orientation of the latter at rest. In addition, this lamella, the reaction torque of which increases rapidly with the angle of torsion, opposes any exaggerated rotation of the rod 9 which could result in one of the main spouts being able to meet a blade intended for another hook (for example the blade located above the rod 9 in fig. 3).

L'invention a donc bien permis de réaliser une mécanique à crochets orientables dans laquelle l'orientation correcte des crochets en position basse ou de repos soit assurée de façon certaine en dépit des vibrations, effets d'inertie et autres actions parasites, ce qui permet de la faire fonctionner à des vitesses plus élevées que celles atteintes jusqu'ici, sans risque de voir apparaître des défauts de sélection.The invention has therefore made it possible to produce a mechanism with orientable hooks in which the correct orientation of the hooks in the low or rest position is ensured in a certain manner despite vibrations, inertia effects and other parasitic actions, which allows to operate it at higher speeds than those reached so far, without the risk of seeing selection faults appear.

Il serait possible de combiner la planche de guidage 25 avec celle de fond 21 au prix, bien entendu, d'un raccourcissement des lamelles 24. On notera encore que l'invention resterait applicable même si la mécanique ne comportait pas de cadre de pas ouvert 20, les becs de retenue 12 étant alors supprimés. Enfin on pourrait aussi utiliser un collet plat sans boucle.It would be possible to combine the guide plate 25 with that of the bottom plate 21 at the cost, of course, of a shortening of the strips 24. It will also be noted that the invention would remain applicable even if the mechanics did not include an open pitch frame 20, the retaining spouts 12 then being eliminated. Finally we could also use a flat collar without buckle.
